基于PLC和数传电台的无线遥控中继站的研究和实现

摘要

偏远地区或山区的供水系统为了实现对水源的监控,需要进行无线信号的传输,因地形原因数据难以实现点到点的直接传送,需要在合适的位置设置数据中继站.因此介绍了一种基于OMRON公司的PLC和MDS OEM数传电台构成的无线遥控中继站的实现方法,并对其进行分析和设计,用较低的成本实现了中继站的功能,满足了用户远程控制的要求.实际运行结果表明方法既满足了监控要求,又降低了设备成本.%In order to continuously monitoring water sources for water supply system in mountainous and remote areas, wireless transmission of data is needed. However, due to the geological configuration in mountainous area, it is difficult to achieve direct transmission of data from point to point, therefore, relay station need to be set at some suitable place to fulfill this goal. This paper introduces a kind of wireless remote control relay station based on OMRON company PLC and MDS OEM data transfer radio, design and analysis are included, and make it satisfies the requirement of user with relatively low cost. Practical operation shown that this new methods not only met the requirement of water sources monitoring, but also reduced the system equipment cost.
